Can a photon ever have negative energy

WebShort answer: a photon is a particle of light. Longer answer: light is energy. Sometimes we think of light as being a wave in the form of an electro-magnetic wave but other times it can be described as a particle. A photon in this case, is 1 unit of light with a variable amount of energy which depends on its frequency. WebFeb 20, 2024 · An individual photon can give all of its energy to an electron.

Is a photon positive, negative or neutral? Naked Science Forum

WebMar 23, 2016 · The photon provides the energy to separate the pre-existing charges within the neutral Hydrogen atom. Another example would be the photoelectric effect (mentioned in previous posts). A photon striking the neutral cathode can eject a negative electron, leaving the cathode with an overall positive charge. WebAlthough a photon is massless, it still has momentum. Einstein's E = mc^2 formula is actually a special case of the special relativity formula E^2 = p^2c^2 + m^2c^4, where p is momentum, m is rest mass, E is energy, and c is the speed of light. If you substitute 0 for m (because a photon is massless), and E = hv (the formula for the energy of a ...
